IMPORTANT:
Pipe joint compounds that resist the action
of natural, L.P., and butane gases must be used.
Test all connections for leaks by brushing on a soapy
water solution (liquid detergent works well).
!
WARNING
Never test for leaks with a flame!!!
Converting from One Family
of Gas to Another _____________________
!
WARNING
(CE Dryers)
This appliance must only be operated with the gas
type indicated on the dryer’s data plate. If the
appliance is converted (gas type changed), a data
plate amendment must be obtained from American
Dryer Corporation (dryer’s serial number is required
to purchase a conversion kit).
IMPORTANT:
Any burner changes or conversions must
be made by a qualified professional.
The dryers manufactured for Belgium, Luxemburg,
Greece, Estonia, Slovak Republic, Iceland, Malta, Poland
and Cyprus cannot be converted from one family of gas to
another.
Conversion from Natural Gas
to Propane or Butane Gas
The following conversion allows the dryer to be operated
with either propane, butane, or LPG. The use of gas valve
kit (ADC P/N 140414) disables the internal regulator of the
gas valve. Therefore, the gas supply is ungoverned and an
external regulator must be provided at the source of the
supply (example L.P. tank) or the gas supply line to the dryer.
The L.P. kit supplied will depend on the country the dryer is
installed in.

Instructions
Disconnect electrical power to the dryer.
Close all shutoff valves (for both top and bottom tumbler) in
dryer’s gas supply line.
IMPORTANT:
The following procedures must be
performed on both top and bottom tumblers.
Open the panels located just below each loading door.
Locate the gas train and disconnect the union, three electrical
plugs, and the gas train mounting screws from the burner.
Carefully slide the gas train out of the gas train enclosure.
(The carbon ignitor located at the far end of the gas train is
very fragile.)
Remove two burner tube mounting screws and remove
burner tube in order to gain access to the orifice.
Using a 3/8” wrench or socket, remove the existing orifice
and replace it with an orifice from the kit.
IMPORTANT:
Use extreme care when removing and
replacing orifice (injector). This orifice (injector) is made
of brass, which is easily damaged.
Reinstall the burner tube onto the burner base.
Use a flat screwdriver to remove the regulator vent cap.
•
For unregulated L.P. gas (most countries):
install
blocking pin (ADC P/N 140414).
•
For regulated L.P. gas (some countries):
remove the
white plastic regulator adjustment screw (under vent
cap). Remove spring under screw and replace with
spring from kit (ADC P/N 140416). Replace regulator
adjustment screw.
